At the beginning of the year, SecureKey announced that it had won an $800,000 grant from the U.S., Department of Homeland Security in support of the company’s development of a blockchain-based digital identity network. Today, the Toronto, Ontario-based authentication specialist unveiled the latest institution to join that network: the National Bank of Canada.

“Adding National Bank to our digital identity network is critical to the success of our ecosystem and brings us one step closer to ensuring consumers are able to prove who they say they are, in person, online, and over the phone,” President and CEO of SecureKey Technologies Greg Wolfond said. Speaking for National Bank, Lionel Pimpin, SVP of Digital Channels, Personal and Commercial Strategies called SecureKey’s network “innovative in the online verification process,” adding that the company’s “blockchain technology will ensure people connect conveniently and privately to their trusted online services.”

With $240 billion in assets, National Bank joins a handful of Canadian FIs that have partnered with SecureKey, such as BMO, CIBC, RBC, and Scotiabank. When the network is fully operational, consumers in Canada will be able to opt-in to the service with their mobile device and use their trusted digital identity credentials that users have established with their preferred partner institution. SecureKey’s network uses IBM’s Blockchain service on top of open source Hyperledger Fabric from the Linux Foundation.

Founded in 2008 and headquartered in Toronto, Ontario, Canada, SecureKey demonstrated its technology at FinovateFall 2012, having won Best of Show two years earlier. The company partnered with IT business and consulting firm Levio last month to add identity authentication services to the latter’s digital transformation projects in Quebec, Canada. Named to Planet Compliance’s RegTech Top 100, SecureKey has raised more than $90 million in total funding and includes Blue Sky Capital and Intel Capital among its investors. Finovate Director of Strategy Lisa Moyle highlighted SecureKey in her look at blockchain and digital identity earlier this year.
